On 1 April 1940, Maathai was born in the village of Ihithe, Nyeri District, in the central highlands of the colony of Kenya. Her family was Kikuyu, the most populous ethnic group in Kenya, and had lived in the area for several generations.[2] Around 1943, Maathai's family relocated to a white-owned farm in the Rift Valley, near the town of Nakuru, where her father had found work.[3] Late in 1947, she returned to Ihithe with her mother, as two of her brothers were attending primary school in the village, and there was no schooling available on the farm where her father worked. Her father remained at the farm.[4] Shortly afterward, at the age of eight, she joined her brothers at Ihithe Primary School.

At age eleven, Maathai moved to St. Cecilia's Intermediate Primary School, a boarding school at the Mathari Catholic Mission in Nyeri.[5] Maathai studied at St. Cecilia's for four years. During this time, she became fluent in English and converted to Catholicism. She was involved with the Legion of Mary, whose members attempted "to serve God by serving fellow human beings."[6] Studying at St. Cecilia's, she was sheltered from the ongoing Mau Mau Uprising, which forced her mother to move from their homestead to an emergency village in Ihithe.[7] When she completed her studies there in 1956, she was rated first in her class, and was granted admission to the only Catholic high school for girls in Kenya, Loreto High School in Limuru.[8]

However, the end of East African colonialism was nearing, and Kenyan politicians, such as Tom Mboya, were proposing ways to make education in Western nations available to promising students. John F. Kennedy, then a United States Senator, agreed to fund such a program through the Joseph P. Kennedy Jr. Foundation, initiating what became known as the Kennedy Airlift or Airlift Africa. Maathai became one of some 300 Kenyans selected to study in the United States in September 1960.[9]

Nothing is more beautiful than cultivating the land at dusk. At that time of day in the central highlands the air and the soil are cool, the sun is going down, the sunlight is golden against the ridges and the green of trees, and there is usually a breeze. As you remove the weeds and press the earth around the crops you feel content, and wish the light would last longer so you could cultivate more. Earth and water, air and waning fire of the sun combine to form the essential elements of life and reveal to me my kinship with the soil. When I was a child I sometimes became so absorbed working in the fields with my machete that I didn’t notice the end of the day until it got so dark that I could no longer differentiate between the weeds and crops. At that point I knew it was time to go home, on the narrow paths that criss crossed the fields and rivers and woodlots.

Upon her return to Kenya, Maathai dropped her Christian name, preferring to be known by her birth name, Wangari Muta.[15] When she arrived at the university to start her new job, she was informed that it had been given to someone else. Maathai believed this was because of gender and tribal bias.[16] After a job search lasting two months, Professor Reinhold Hofmann, from the University of Giessen in Germany, offered her a job as a research assistant in the microanatomy section of the newly established Department of Veterinary Anatomy in the School of Veterinary Medicine at University College of Nairobi.[17] In April 1966, she met Mwangi Mathai, another Kenyan who had studied in America, who would later become her husband.[18] She also rented a small shop in the city, and established a general store, at which her sisters worked. In 1967, at the urging of Professor Hofmann, she traveled to the University of Giessen in Germany in pursuit of a doctorate. She studied both at Giessen and the University of Munich.

In the spring of 1969, she returned to Nairobi to continue her studies at the University College of Nairobi as an assistant lecturer. In May, she and Mwangi Mathai were married.[19] Later that year, she became pregnant with her first child, and her husband campaigned for a seat in Parliament, narrowly losing. During the course of the election, Tom Mboya, who had been instrumental in founding the program which sent her overseas, was assassinated. This led to President Kenyatta effectually ending multi-party democracy in Kenya. Shortly after, her first son, Waweru, was born.[20] In 1971, she became the first Eastern African woman to receive a Ph.D, her doctorate in veterinary anatomy,[13] from the University College of Nairobi, which became the University of Nairobi the following year. She completed her dissertation on the development and differentiation of gonads in bovines.[21] Her daughter, Wanjira, was born in December 1971.

Maathai continued to teach at Nairobi, becoming a senior lecturer in anatomy in 1975—, chair of the Department of Veterinary Anatomy in 1976 and associate professor in 1977. She was the first woman in Nairobi appointed to any of these positions.[22] During this time, she campaigned for equal benefits for the women working on the staff of the university, going so far as to attempt to turn the academic staff association of the university into a union, in order to negotiate for benefits. The courts denied this bid, but many of her demands for equal benefits were later met.[23] In addition to her work at the University of Nairobi, Maathai became involved in a number of civic organizations in the early 1970s. She was a member of the Nairobi branch of the Kenya Red Cross Society, becoming its director in 1973. She was a member of the Kenya Association of University Women. Following the establishment of the Environment Liaison Centre in 1974, Maathai was asked to be a member of the local board, eventually becoming the chair of the board. The Environment Liaison Centre worked to promote the participation of non-governmental organizations in the work of the United Nations Environment Programme (UNEP), whose headquarters was established in Nairobi following the United Nations Conference on the Human Environment held in Stockholm in 1972. Maathai also joined the National Council of Women of Kenya (NCWK).[24] Through her work at these various volunteer associations, it became evident to Maathai that the root of most of Kenya's problems was environmental degradation.[25]

We hoped that these elections would provide the people of Kenya with a fairer and truer representation of their aspirations and beliefs. To our dismay and despair, however, the elections were the most disturbing and distorted in Kenya’s history. The government introduced a highly controversial system of “que” voting. Voters lined up behind their candidate and election officials counted each line and then told the people to go home. When election officials announced the winner, it was often the candidate with the shortest line of voters behind him! Since the voters were at home, there was nothing that could be done: The winner had been declared. The vote- rigging was so blatant that people who had lost their races were declared the winners in broad daylight with no embarrassment whatsoever on the part of the government… I knew that we could not live with a political system that killed creativity, nurtured corruption, and produced people who were afraid of their own leaders. It would be only a matter of time before the government and I came in to further conflict…

Wangari Muta Maathai – Unbowed, pp. 182–183.

In 1974, Maathai's family expanded to include her third child, Muta. Her husband campaigned again for a seat in Parliament, hoping to represent the Lang'ata constituency, and won. During his campaign, he had promised to find jobs to limit the rising unemployment in Kenya. These promises led Maathai to connect her ideas of environmental restoration to providing jobs for the unemployed, and led to the founding of Envirocare Ltd., a business that involved the planting of trees to conserve the environment, involving ordinary people in —the ——process. This led to the planting of her first tree nursery, collocated with a government tree nursery in Karura Forest. Envirocare ran into multiple problems, primarily dealing with funding. The project failed, however, through conversations concerning Envirocare and her work at the Environment Liaison Centre, UNEP made it possible to send Maathai to the first UN conference on human settlements, known as Habitat I, in June 1976.[26]

In 1977, Maathai spoke to the NCWK concerning her attendance at Habitat I. She proposed further tree planting, which the council supported. On 5 June 1977, marking World Environment Day, the NCWK marched in a procession from Kenyatta International Conference Centre in downtown Nairobi to Kamukunji Park on the outskirts of the city where they planted seven trees in honor of historical community leaders. This was the first "Green Belt" which was first known as the "Save the Land Harambee" and then became the Green Belt Movement.[27] Maathai encouraged the women of Kenya to plant tree nurseries throughout the country, searching nearby forests for seeds to grow trees native to the area. She agreed to pay the women a small stipend for each seedling which was later planted elsewhere.[28]

Maathai and her husband, Mwangi Mathai, separated in 1977. After a lengthy separation, Mwangi filed for divorce in 1979. Mwangi was said to have believed Wangari was "too strong-minded for a woman" and that he was "unable to control her". In addition to naming her as "cruel" in court filings, he publicly accused her of adultery with another Member of Parliament,[29] which in turn was thought to cause his high blood pressure and the judge ruled in Mwangi's favour. Shortly after the trial, in an interview with Viva magazine, Maathai referred to the judge as either incompetent or corrupt.[29] The interview later led the judge to charge Maathai with contempt of court. She was found guilty and sentenced to six months in jail. After three days in Lang'ata Women's Prison in Nairobi, her lawyer formulated a statement which the court found sufficient for her release. Shortly after the divorce, her former husband sent a letter via his lawyer demanding that Maathai drop his surname. She chose to add an extra "a" instead.[30][31]

The divorce had been costly, and with lawyers' fees and the loss of her husband's income, Maathai found it difficult to provide for herself and her children on her university wages. An opportunity arose to work for the Economic Commission for Africa through the United Nations Development Programme. As this job required extended travel throughout Africa and was based primarily in Lusaka, Zambia, she was unable to bring her children with her. Maathai chose to send them to her ex-husband and take the job. While she visited them regularly, they lived with their father until 1985.[32]

In 1979, shortly after the divorce, Maathai ran for the position of chairman of the National Council of Women of Kenya (NCWK), an umbrella organization consisting of many different women's organizations in the country. The then newly elected President of Kenya, Daniel arap Moi, was attempting to limit the amount of influence those of the Kikuyu ethnicity held in the country, including in volunteer civic organizations such as the NCWK. She lost this election by three votes, but was overwhelmingly chosen to be the vice-chairman of the organization. The following year, Maathai again ran for chairman of the NCWK. Again she was opposed, she believes, by the government. When it became apparent that Maathai was going to win the election, Maendeleo Ya Wanawake, a member organization which represented a majority of Kenya's rural women and whose leader was close to arap Moi, withdrew from the NCWK. Maathai was then elected chairman of the NCWK unopposed. However, Maendeleo Ya Wanawake came to receive a majority of the financial support for women's programs in the country, and NCWK was left virtually bankrupt. Future funding was much more difficult to come by, but the NCWK survived by increasing its focus on the environment and making its presence and work known. Maathai continued to be reelected to serve as chairman of the organization every year until she retired from the position in 1987.[33]

It soon became obvious that politics was at play again. The ruling party didn’t want me in Parliament and had figured out a way to stop me from getting there. Once again, I decided to fight by taking the authorities to court and challenging their reason for disqualifying me, which I knew to be completely illegal. The court sat at nine o’clock on a Saturday morning, but I was required to present my candidacy papers by noon that same day in Nyeri, which is nearly a three-hour drive from Nairobi. Seeing that it would be impossible for me to meet the deadline if I drove, some friends had hired a plane to take me to Nyeri as soon as the court rendered its verdict. By the time the Judge made his final ruling, disqualifying me from running for parliament, it was nearly midday. Even with the plane and favorable ruling, I would have arrived in Nyeri too late. My case, like many others, demonstrated a miscarriage of justice that was frequent at that time in Kenya and that led me, later, to be involved in the pro-democracy movement. Once again, I had lost in court. I would not be able to run.

Wangari Muta Maathai – Unbowed, pp. 161.

In 1982, the Parliamentary seat representing her home region of Nyeri was open, and Maathai decided to campaign for the seat. As required by law, she resigned her position with the University of Nairobi to campaign for office. The courts decided that she was ineligible to run for office because she had not re-registered to vote in the last presidential election in 1979. Maathai believed this to be false and illegal, and brought the matter to court. The court was to meet at nine in the morning, and if she received a favourable ruling, was required to present her candidacy papers in Nyeri by three in the afternoon that same day. The judge disqualified her from running on a technicality. [clarification needed] When she requested her job back, she was denied. As she lived in university housing and was no longer a staff member, she was evicted.[34]

Maathai moved into a small home she had purchased years before, and focused on the NCWK while she searched for employment. In the course of her work through the NCWK, she was approached by Wilhelm Elsrud, executive director of the Norwegian Forestry Society. He wished to partner with the Green Belt Movement and offered her the position of coordinator. Employed again, Maathai poured her efforts into the Green Belt Movement. Along with the partnership for the Norwegian Forestry Society, the movement had also received "seed money" from the United Nations Voluntary Fund for Women. These funds allowed for the expansion of the movement, for hiring additional employees to oversee the operations, and for continuing to pay a small stipend to the women who planted seedlings throughout the country. It allowed her to refine the operations of the movement, paying a small stipend to the women's husbands and sons who were literate and able to keep accurate records of seedlings planted.[35]

Although I was a highly educated woman, it did not seem odd to me to work with my hands, often with my knees on the ground, alongside rural woman. Some politicians and others in the 1980s and 1990s ridiculed me for doing so. But I had no problem with it, and the rural women both accepted and appreciated that I was working with them to improve their lives and the environment. After all, I was a child of the same soil. Education, if it means anything, should not take people away from land, but instill in them even more respect for it, because educated people are in a position to understand what is being lost. The future of the planet concerns all of us, and we should do what we can to protect it. As I told the foresters, and the women, you don't need a diploma to plant a tree.

Wangari Muta Maathai – Unbowed, pp. 137–138.

The UN held the third global women's conference in Nairobi. During the conference, Maathai arranged seminars and presentations to describe the work the Green Belt Movement was doing in Kenya. She escorted delegates to see nurseries and plant trees. She met Peggy Snyder, the head of UNIFEM, and Helvi Sipilä, the first woman appointed a UN assistant secretary general. The conference helped to expand funding for the Green Belt Movement and led to the movement's establishing itself outside of Kenya. In 1986, with funding from UNEP, the movement expanded throughout Africa and led to the foundation of the Pan-African Green Belt Network. Forty-five representatives from fifteen African countries travelled to Kenya over the next three years to learn how to set up similar programs in their own countries to combat desertification, deforestation, water crises, and rural hunger. The attention the movement received in the media led to Maathai's being honoured with numerous awards. The government of Kenya, however, demanded that the Green Belt Movement separate from the NCWK, believing the latter should focus solely on women's issues, not the environment. Therefore, in 1987, Maathai stepped down as chairman of the NCWK and focused her attention on the newly separate non-governmental organization.[36]

In the latter half of the 1980s, the Kenyan government came down against Maathai and the Green Belt Movement. The single-party democracy opposed many of the positions the movement held regarding democratic rights. The government invoked a colonial-era law prohibiting groups of more than nine people from meeting without first obtaining a government license. In 1988, the Green Belt Movement carried out pro-democracy activities such as registering voters for the election and pressing for constitutional reform and freedom of expression. The government carried out electoral fraud in the elections to maintain power, according to Maathai.[37]

In October 1989, Maathai learned of a plan to construct the 60-story Kenya Times Media Trust Complex in Uhuru Park. The complex was intended to house the headquarters of KANU, the Kenya Times newspaper, a trading centre, offices, an auditorium, galleries, shopping malls, and parking space for two thousand cars. The plan also included a large statue of President Daniel arap Moi. Maathai wrote many letters in protest to, among others, the Kenya Times, the Office of the President, the Nairobi city commission, the provincial commissioner, the minister for environment and natural resources, the executive directors of UNEP and the Environment Liaison Centre International, the executive director of the UN Educational, Scientific and Cultural Organization (UNESCO), the ministry of public works, and the permanent secretary in the department of international security and administration all received letters. She wrote to Sir John Johnson, the British high commissioner in Nairobi, urging him to intervene with Robert Maxwell, a major shareholder in the project, equating the construction of a tower in Uhuru Park to such construction in Hyde Park or Central Park and maintaining that it could not be tolerated.[38]

When I see Uhuru Park and contemplate its meaning, I feel compelled to fight for it so that my grandchildren may share that dream and that joy of freedom as they one day walk there.

Wangari Muta Maathai – Unbowed, p. 192.

The government refused to respond to her inquiries and protests, instead responding through the media that Maathai was "a crazy woman"; that denying the project in Uhuru Park would take more than a small portion of public park land; and proclaiming the project as a "fine and magnificent work of architecture" opposed by only the "ignorant few." On 8 November 1989, Parliament expressed outrage at Maathai's actions, complaining of her letters to foreign organizations and calling the Green Belt Movement a bogus organization and its members "a bunch of divorcees". They suggested that if Maathai was so comfortable writing to Europeans, perhaps she should go live in Europe.[39]

Despite Maathai's protests, as well as popular protest growing throughout the city, ground was broken at Uhuru Park for construction of the complex on 15 November 1989. Maathai sought an injunction in the Kenya High Court to halt construction, but the case was thrown out on 11 December. In his first public comments pertaining to the project, President Daniel arap Moi stated that those who opposed the project had "insects in their heads". On 12 December, in Uhuru Park, during a speech celebrating independence from the British, President Moi suggested Maathai be a proper woman in the African tradition and respect men and be quiet.[40] She was forced by the government to vacate her office, and the Green Belt Movement was moved into her home. The government then audited the Green Belt Movement in an apparent attempt to shut it down. Despite all this, her protests, the government's response – and the media coverage it garnered – led foreign investors to cancel the project in January 1990.[41][42]

In January 1992, it came to the attention of Maathai and other pro-democracy activists that a list of people were targeted for assassination and that a government-sponsored coup was possible. Maathai's name was on the list. The pro-democracy group, known as the Forum for the Restoration of Democracy (FORD), presented its information to the media, calling for a general election. Later that day, Maathai received a warning that one of their members had been arrested. Maathai decided to barricade herself in her home. Shortly thereafter, police arrived and surrounded the house. She was besieged for three days before police cut through the bars she had installed on her windows, came in, and arrested her. She and the other pro-democracy activists who had been arrested were charged with spreading malicious rumours, sedition and treason. After a day and a half in jail, they were brought to a hearing and released on bail. A variety of international organizations and eight senators (including Al Gore and Edward M. Kennedy) put pressure on the government of Kenya to substantiate the charges against the pro-democracy activists or risk damaging relations with the United States. In November 1992, the government of Kenya dropped the charges.[43]

On 28 February 1992, while released on bail, Maathai and others took part in a hunger strike in a corner of Uhuru Park, which they labelled Freedom Corner, to pressure the government to release political prisoners. After four days of the hunger strike, on 3 March 1992, the police forcibly removed the protesters. Maathai and three others were knocked unconscious by police and hospitalized.[44]PresidentDaniel arap Moi called her "a mad woman" who is "a threat to the order and security of the country".[45] The attack drew international criticism. The US State Department said it was "deeply concerned" by the violence and by the forcible removal of the hunger strikers.[46] When the political prisoners were not released, the protesters – mostly mothers of those in prison – moved their protest to All Saints Cathedral, seat of the Anglican Archbishop in Kenya, across from Uhuru Park. The protest there continued, with Maathai contributing frequently, until early 1993, when the prisoners were finally released.[47]

During this time, Maathai was being recognized with various awards internationally, but the government of Kenya did not appreciate her work. In 1991 she received the Goldman Environmental Prize in San Francisco and the Hunger Project's Africa Prize for Leadership in London. CNN aired a three-minute segment concerning the Goldman prize, but when it aired in Kenya, that segment had been edited out. In June 1992, during the lengthy protest at Uhuru Park, both Maathai and President arap Moi travelled to Rio de Janeiro for the UN Conference on Environment and Development (Earth Summit). The government of Kenya accused Maathai of inciting women and encouraging them to strip at Freedom Corner, urging that she not be allowed to speak at the summit. Despite this, Maathai was chosen to be a chief spokesperson at the summit.[48]

During the first multi-party election of Kenya, in 1992, Maathai strove to unite the opposition and promote free and fair elections in Kenya. The Forum for the Restoration of Democracy (FORD) had fractured into FORD-Kenya (led by Oginga Odinga) and FORD-Asili (led by Kenneth Matiba); Mwai Kibaki, the former vice president, had left the ruling Kenya African National Union (KANU) party, and formed the Democratic Party. Maathai and many others believed such a fractured opposition would lead to KANU's retaining control of the country, so they formed the Middle Ground Group in an effort to unite the opposition. Maathai was chosen to serve as its chairperson. Also during the election, Maathai and like-minded opposition members formed the Movement for Free and Fair Elections. Despite their efforts, the opposition did not unite, and the ruling KANU party used intimidation and state-held media to win the election, retaining control of parliament.[49]

It is often difficult to describe to those who live in a free society what life is like in an authoritarian regime. You don't know who to trust. You worry that you, your family, or your friends will be arrested and jailed without due process. The fear of political violence or death, whether through direct assassinations or targeted “accidents”, is constant. Such was the case in Kenya, especially during the 1990s.

Wangari Muta Maathai – Unbowed, p. 206.

The following year, ethnic clashes occurred throughout Kenya. Maathai believed they were incited by the government, who had warned of stark consequences to multi-party democracy. Maathai travelled with friends and the press to areas of violence in order to encourage them to cease fighting. With the Green Belt Movement she planted "trees of peace", but before long her actions were opposed by the government. The conflict areas were labeled as "no go zones", and in February 1993 the president claimed that Maathai had masterminded a distribution of leaflets inciting Kikuyus to attack Kalenjins. After her friend and supporter Dr. Makanga was kidnapped, Maathai chose to go into hiding. While in hiding, Maathai was invited to a meeting in Tokyo of the Green Cross International, an environmental organization recently founded by former Soviet leader Mikhail Gorbachev. When Maathai responded that she could not attend as she did not believe the government would allow her to leave the country and she was in hiding, Gorbachev pressured the government of Kenya to allow her to travel freely. President arap Moi denied limiting her travel, and she was allowed to leave the country, although too late for the meeting in Tokyo. Maathai was again recognized internationally, and she flew to Scotland to receive the Edinburgh Medal in April 1993. In May she went to Chicago to receive the Jane Addams International Women's Leadership Award, and in June she attended the UN's World Conference on Human Rights in Vienna.[50]

During the elections of 1997, Maathai again wished to unite the opposition in order to defeat the ruling party. In November, less than two months before the election, she decided that she would run for parliament and for president as a candidate of the Liberal Party. Her intentions were widely questioned in the press; many believed she should simply stick to running the Green Belt Movement and stay out of politics. On the day of the election, a rumour that Maathai had withdrawn from the election and endorsed another candidate was printed in the media. Maathai garnered few votes and lost the election.[51]

In the summer of 1998, Maathai learned of a government plan to privatize large areas of public land in the Karura Forest, just outside Nairobi, and give it to political supporters. Maathai protested against the privatization through letters to the government and the press. She went with the Green Belt Movement to Karura Forest, planting trees and protesting the destruction of the forest. On 8 January 1999, a group of protesters including Maathai, six opposition MPs, journalists, international observers, and Green Belt members and supporters returned to the forest to plant a tree in protest. The entry to the forest was guarded by a large group of men. When she tried to plant a tree in an area that had been designated to be cleared for a golf course, the group was attacked. Many of the protesters were injured, including Maathai, four MPs, some of the journalists, and German environmentalists. When she reported the attack to the police, they refused to return with her to the forest to arrest her attackers. However, the attack had been filmed by Maathai's supporters, and the event provoked international outrage.[41][52] Student protests broke out throughout Nairobi, and some of these groups were violently broken up by the police. Protests continued until 16 August 1999, when the president announced that he was banning all allocation of public land.[53]

In 2001, the government was again planning to take public forest land and give it to its supporters. While protesting the land-grab and collecting petition signatures on 7 March 2001, in Wang'uru village near Mount Kenya, Maathai was again arrested. The following day, following international and popular protest at her arrest, she was released without being charged. On 7 July 2001, shortly after planting trees at Freedom Corner in Uhuru Park in Nairobi to commemorate Saba Saba Day, Maathai was again arrested. Later that evening, she was again released without being charged.[54] In January 2002, Maathai returned to teaching as the Dorothy McCluskey Visiting Fellow for Conservation at the Yale University's School of Forestry and Environmental Studies. She remained there until June 2002, teaching a course on sustainable development focused on the work of the Green Belt Movement.[55]

Wangari Maathai was awarded the 2004 Nobel Peace Prize for her "contribution to sustainable development, democracy and peace".[58] She had received a call from Ole Danbolt Mjos, chair of the Norwegian Nobel Committee, on 8 October informing her of the news.[59][60] She became the first African woman, and the first environmentalist, to win the prize.

I was not prepared to learn that I had been awarded the Nobel Peace Prize; I wonder whether anybody ever is. The news hit me like a thunderbolt. How was I supposed to handle it? How did this happen? How did they find such a person as me? I could hardly believe it . It was clear now why the Norwegian ambassador had called. “I am being informed that I have won the Nobel Peace Prize,” I announced to myself and those around me in the car with a smile as I pulled the cell phone away from my ear and reconnected with my fellow passengers. They knew it was not a joke because happiness was written all over my face. But at the same time, tears steamed from my eyes and onto my cheeks as I turned to them. They, too, were now smiling broadly, some cheering and hugging me as if to both comfort and congratulate me, letting my tears fall on their shoulders and hiding my face from some of my staff, whom they felt shouldn’t see me cry. But these were tears of great joy at an extraordinary moment!

Maathai stood up courageously against the former oppressive regime in Kenya. Her unique forms of action have contributed to drawing attention to political oppression—nationally and internationally. She has served as inspiration for many in the fight for democratic rights and has especially encouraged women to better their situation.

In a 2004 interview with Time, in response to questions concerning that report, Maathai replied, "I have no idea who created AIDS and whether it is a biological agent or not. But I do know things like that don't come from the moon. I have always thought that it is important to tell people the truth, but I guess there is some truth that must not be too exposed," and when asked what she meant, she continued, "I'm referring to AIDS. I am sure people know where it came from. And I'm quite sure it did not come from the monkeys."[62] In response she issued the following statement:

“

I have warned people against false beliefs and misinformation such as attributing this disease to a curse from God or believing that sleeping with a virgin cures the infection. These prevalent beliefs in my region have led to an upsurge in rape and violence against children. It is within this context, also complicated by the cultural and religious perspective, that I often speak. I have therefore been shocked by the ongoing debate generated by what I am purported to have said. It is therefore critical for me to state that I neither say nor believe that the virus was developed by white people or white powers in order to destroy the African people. Such views are wicked and destructive.[63]

In August 2006, then United States SenatorBarack Obama traveled to Kenya. His father was educated in America through the same program as Maathai. She and the Senator met and planted a tree together in Uhuru Park in Nairobi. Obama called for freedom of the press to be respected, saying, "Press freedom is like tending a garden; it continually has to be nurtured and cultivated. The citizenry has to value it because it's one of those things that can slip away if we're not vigilant." He deplored global ecological losses, singling out President George W. Bush's refusal to join the United Nations Framework Convention on Climate Change (UNFCCC) and its subsidiary, the Kyoto Protocol.[66]

Maathai was defeated in the Party of National Unity's primary elections for its parliamentary candidates in November 2007 and chose to instead run as the candidate of a smaller party.[67] She was defeated in the December 2007 parliamentary election. She called for a recount of votes in the presidential election (officially won by Mwai Kibaki, but disputed by the opposition) in her constituency, saying that both sides should feel the outcome was fair and that there were indications of fraud.[68]

In June 2009, Maathai was named as one of PeaceByPeace.com's first peace heroes.[69] Until her death in 2011, Maathai served on the Eminent Advisory Board[70] of the Association of European Parliamentarians with Africa (AWEPA).

In 2012, the Collaborative Partnership on ForestsCPF, an international consortium of 14 organizations, secretariats and institutions working on international forest issues, launched the inaugural Wangari Maathai Award to honour and commemorate an extraordinary woman who championed forest issues around the world. The USD20,000 award is given in recognition of outstanding contributions made by an individual to preserve, restore and sustainably manage forests and to communicate the key role forests play in rural livelihoods and the environment across generations.

The 2012 inaugural winner of the Award[72] was Narayan Kaji Shrestha. Shrestha is recognized as one of the main architects of the community forestry movement in Nepal, which he has spent three decades promoting and which has contributed significantly to restoring forest resources in the country. He guided early attempts to create a more participatory approach to community decision-making, reaching out to women and low-caste villagers and initiating the country’s first user-managed community forestry group. He provided leadership to the national organization that later became the Federation of Community Forestry Users in Nepal and continues to be a guide and mentor to many practitioners and leaders involved in participatory resource management. The jury also awarded Kurshida Begum of Bangladesh an Honourable Mention prize for her work helping women in her village form a community patrol group alongside forest department guards to protect the forests and biodiversity of the Tenkaf Wildlife Sanctuary from illegal logging and poaching.
